Well, how about this! I don't know how good the read is going to be, and it's a fiction contemporary American mystery of the "Trash 'n' Treasures" series. The book is called Antiques Disposal, by Barbara Allan.
Now, lately flea market and antique store mystery books have been very popular -- there are quite a few series out there, and my sister loves to read them since she's an Ebay/antiques store dealer.
I was browsing on Amazon for the new revised expanded edition of Jelly Roll,Bix and Hoagy which is supposed to be released Janaury 2012, and just typing in Bix Beiderbecke under the books heading, this little novel was listed. In my Search Inside, this story seems to be about an antiques dealer divorcee and her elderly mom discovering what is supposed to be Bix's cornet [yeah yeah, we'll all giggle and snort and roll our eyes, but it's just a story and it's not bad writing from what I'm reading -- certainly not a vanity press book like that awful thing I bought --and promptly, contemptuously discarded-- around 5 years ago.]
So, it might be cute, or amusing, or downright fun. I don't suspect I'll feel ripped off since the reviews are a jolly reaction and this writer has a series out -- it doesn't appear to be hack writing, at any rate.
Sort of those speculative "What if" stories, "Wouldn't it be neat if someone junk-hunting found an unknown artifact of Bix's, and all sorts of collectors wanted in on it and mischief ensues. . .. "
